I had read some articles had encapsulated the oxygen in liposomes and injected parenterally. is it possible to encapsulate and how about the stability and what was the method..
It sounds interesting, but how could be possible create a double layer of phospholipids around a gas particle, where also water molecules need to be included ?
Hi, thank you for sharing this paper. I read it, but still it is not clear to me what is the preparation method of liposomes. As it is said in the paragraph "LOM suspension preparation and characterization", a combination of different PEGilated lipids and surfactants were hydrated in 0.9% sodium chloride. LOMs were manufactured with a customized apparatus that included sonication, size isolation by flotation, and concentration by centrifugation."
I am interested in this field because I have never heard about gas entrapped particles in the DDS systems.
About liposomes, generally the lipidic layer is self-assembled around a water droplet, but how could this happen spontaneously around a gas particle?
In addition to the ingredients and type of liposome / nanoliposome employed (unilamellar, multilamellar, etc.), the parameters influencing manufacture and stability of the mentioned product are:
*Type of surfactant(s) / emulsifier(s) used;
*The equipment used to generate gas bubbles of right size and speed / rate of bubble generation;
*The suspension media (pH, osmolarity);
*Process temperature;
*agitation speed;
*Rate and sequence of introducing surfactants / emulsifiers and ingredients of liposomes to the system;
*Polymers / any other ligands used to cover the surface of liposomes externally;
*...
I hope these explanations help; otherwise let me know.
